Nice that you found a solution and post it.

I would boot a Linux live system from an USB-Stick and have a look how the SATA-Ports are shown to the system. Then you will not have to guess and can give the loader exactly information about the SATA-Controller/-Ports.

If you just booted from the usb-stick and not have installed DSM via the assistant than you can't login to the system. If DSM is installed you can login as "root" if you wish or with "admin" and change to root afterwards (the same way you use if you login via ssh).

Can you please write is the transfer speed of this setup is sufficient for you? I have a similar setup (the only difference is that I make a complete passthrough of the H310 HBA instead of making RDMs of the single disks) and think about updating from 6.2 to 6.2.1. But I want to make this step only if the transfer speed is similar to the 6.2-setup.

Thank you for the summarization and sharing your experiences!

@flyride: Thanks for the link to your article from march! I missed it and the information in it is very useful.

Thanks for the pictures! It seems that you are right with the idea of the internal hdd as a "save harbour" for the dsm itself. The dsm partition is a mirror and the "repair" forces a sync which seems to be needed as the usb harddisks are recognised slower than internal hdd harddisks. But if this is the only issue I think you can live with it especially as this is only a backup system.

@shrabok: Thank you very much for your article and your experiences with this idea. I have a few questions: - Do your end configuration is a SHR1 Volume consisting the 2 TB internal hard disk AND all external USB-Drives or do you use the internal drive as a "basic" drive without redundancy and have made a SHR1-Array only with the external USB-Drives? - Does your SHR1 Volume survive a reboot without breaking the the array? Or are you forced to rebuild the array after every reboot? - do you get issues with the sleep mode of the USB drives? Most of them have a real aggressive power save mode build in and maybe this will lead to problems. For my USB drives (which are currently working as normal external USB drives) I have written a little script which runs at start to disable the sleep mode (or better explained to lower the load/unload-cycles).

Nice finding. i hope there will be some time an update for the vmxnet3 driver as it has much advantages over the pure intel driver.

Sorry for posting in english here: It works very well! Thank you very much! Copy modules and set the correct rights: cp /volume2/data/HP_AMS_DSM_6.2/amsHelper /sbin chown root:root /sbin/amsHelper chmod 755 /sbin/amsHelper cp /volume2/data/HP_AMS_DSM_6.2/hpilo.ko /lib/modules chown root:root /lib/modules/hpilo.ko chmod 644 /lib/modules/hpilo.ko Then activate it: insmod /lib/modules/hpilo.ko /sbin/amsHelper -I0 -M1,5,14,16,18,23,99 Automatic activation after every boot: - Create a startup-script with the following content in \usr\local\etc\rc.d\S99HP-AMS.sh #!/bin/sh modprobe hpilo /sbin/amsHelper -I0 -M1,5,14,16,18,23,99 (make sure to set the startup-script to 755 ) I attached the result as a picture. All sensors were read and the fan is going down to 10%. :-)

Sorry but you have to do your homework and read by yourself a little bit with the given information. In short: "in IT-Mode the HBA (this is the H200) exposes all connected harddisks as themselves to the operating system whereas the original firmware sums the harddisks up in, for example a raid 1 (mirror) and exposes this raid 1 to the operating system (which you don't want for the usage in DSM). Best of luck to you.

No, I don't know the card you posted. I only want to give a hint which cards are working proved well. This is the manual I used to flash: https://techmattr.wordpress.com/2013/08/30/sas-hba-crossflashing-or-flashing-to-it-mode/ Of course as I said: it is hard if you never made such processes but I hope you get what I mean. Maybe you can buy an already flashed Dell H200 in IT-Mode on eBay? A quick search for "dell h200 it mode" gives me multiple results. Here a 2 examples where you can see what I mean: https://www.ebay.com/itm/Dell-H200-6Gbps-SAS-HBA-w-LSI-9211-8i-P20-IT-Mode-for-ZFS-FreeNAS-unRAID/163142320696 https://www.ebay.com/itm/Dell-PERC-H200-SAS-Controller-IT-mode-2x-cable-SFF-8087-to-4x-SAS-SATA/123126065790 These cards are working (if they are in good condition of course).

My suggestion is: use an IBM M1015 or Dell H200/H310 (these adapters I use by myself) flashed to IT-firmware. It's a little hard to read through the howto if you never made this before but it works for me for about 3 years now. Afterwards you get 8 internally usable ports which are recognised by DSM.

I am waiting for this too as I have no use for plex and my Xpenology 6.1.7 under Vmware 6.5 on HP Microserver Gen8 is working awesome.

Did you use the VMXNET3 or E1000 as vNIC?
